有机聚合物英语:Polymer)是指具有非常大的分子量的化合物,分子间由结构单位(structural unit)、或单体由共价键连接在一起 。 这个聚合物(polymer)是出自于希腊字:polys代表的是,而meros 代表的是小单位(part),所以很多小单位链接在一起的这种特别的分子,我们称之为聚合物。可以参考塑胶、DNA和高分子。

IUPAC definition

Substance composed of macromolecules.

Note: Applicable to substance macromolecular in nature like cross-linked
systems that can be considered as one macromolecule.

A polymer (/ˈpɒlmər/; Greek poly-, "many" + -mer, "parts") is a large molecule, or macromolecule, composed of many repeated subunits. Because of their broad range of properties, both synthetic and natural polymers play an essential and ubiquitous role in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass relative to small molecule compounds produces unique physical properties, including toughness, viscoelasticity, and a tendency to form glasses and semicrystalline structures rather than crystals.
